Maple Tree Seeds As Nano Air Vehicles
Unarmed air vehicles (UAVs) are becoming increasingly important in warfare. The company AeroVironment, which makes drones already being used in combat, looked to hummingbirds for one of its latest creations. Whereas the tiny bird hovers by flapping its wings 80 times per second, its carbon fiber-based counterpart flaps at just a quarter that speed but still manages to hover. Equipped with a small camera, the Nano Hummingbird is designed to perform reconnaissance in cities.
